HOW CUTTING IS A HOT TOPIC
Saws have been around since the dawn of time even before history has tried to record itself. The primitive tools that man had created never ceased to include a tool for cutting, and even until now it is a requirement to every craftsman, builder, woodworker, carpenter, and any other profession or trade that’s similar.
From the most basic of sharp-edged stone, weapons made cutting tool – to the crude but a useful hand saw – to the two men saw – to the mechanical saw we have today. Each new development has improved what was once a mere tool to separate a thick piece of wood.

WHAT IS A CHOP SAW?
When a method to replace conventional cutting tools was discovered, the chop saw was a revolutionary invention. Crude saws required men (or women) to exert a good amount of manual labor before they could separate a material in two (usually wood and other hard materials.) When the chop saw was created, this took away the need to exert hard work.
A chop saw replaces a regular manual saw by having a round metal saw that spins when connected to a power source (Usually an electric outlet.) It’s a bit heavy but is enormously better at cutting!

WHAT DOES A CHOP SAW DO?
A chop saw is a mechanical saw that specializes in cutting at a forty-five-degree angle. It is a “power tool” amply named because it powers through cutting even the hardest and thickest of materials. Usually used to cut steel and other strong alloys, a chop saw breezes through and separates them no problem.
As said it only does cut at one angle (forty-five degrees) and needs a source of power (generator or outlet.) But because it is so strong, you seldom see workshops without one. With just one push of a button and a pushing down of the saw’s mechanism, the material you position it to be cut will eventually separate with no need to exert unnecessary effort whatsoever!
